Here’s an interesting What-If. Two years before Taffin, Pierce was in a movie directed by John McTiernan, called Nomads. The same year that Taffin came out, McTiernan directed Die Hard, which famously (after the usual movie stars turned it down) cast in the lead role an actor who was until then known as a tv actor and who was one of the leads in a light-hearted detective show, with a “Will they/wont they” dynamic between the male and female leads. Yes, he went with the male star of Moonlighting but what if he’d instead chosen the star of Remington Steele?
We know that McT and Brosnan would later reunite for The Thomas Crown Affair, so it’s not like there would have been an objection on principle or a personal level.
I don’t think Pierce would’ve been as good a McClane as Bruce, but imagine he’s cast in the role, Bruno remains a tv star and what happens Bond? If Die Hard With A Vengeance still goes into production for a 1995 release, does this mean Brosnan can’t do Goldeneye? Would Robert Davi still appear in Die Hard and LTK? Would Goldeneye still steal DH 2’s ejector seat escape? So many other questions!
